So, I bought a donor 160hp 12v and 47RH for my Excursion Cummins swap. The trans has about 30,000 miles on a Jasper rebuild from 2015. My goal is to do minimum mods possible to give this thing a fighting chance without going deep into the transmission. If you guys think adding a shift kit or anything would end it's life early, I'll toss the trans in the way it is.
I called Jasper and to my surprise the fella there actually gave me some build info on the trans. He claimed it has 5 pinion planetary, 8 clutches instead of 5 in the overdrive unit, a billet cover single disk with stock internals, all the transmission updates, and extra clutches somewhere else that I couldn't make out, maybe he said forward drum. Anyways, the fluid is spotless and I plan to drop the pan this week and see what's inside.
For now, I need it to hold between 300-400hp in a 8500lb Excursion with 3.73's. Don't plan to tow much of anything.
Single or Double Deep Pan?
Transgo kit?
Billet strut, anchor, servo, accumulator?
I feel like a triple disk, input shaft, and aftermarket valvebody is unnecessary at this point, but I don't claim to be an expert. I've been reading what I can, but time is working against me. I'm trying to get this project on the road in the next 2-3 weeks.
Thanks guys!
